Oversize piston kit, fits 1996 and later KLR650. Forged, lightweight, 3.00mm over stock. Premium rings and wrist pin. Requires cylinder machining. This kit includes required gaskets : fitted head gasket, base gasket, exhaust headpipe crush copper gasket, cam chan tensioner gasket. Lighter and smoother than the factory setup. If you have an oil user this is a good way to go.

Improved performance and smoother engine. Much greater difference than expected for a 41cc increase.

This kit originally designed to be used when you wear out your 685. You can also go straight to the 692! This is a big as you should take the stock liner.

We are supplying Kawasaki OEM gaskets. The head gasket is cut for the oversize bore.

IMPORTANT - these are considered racing parts, and there is no warranty. The performance and function is entirely dependant on the quality of the bore and honing, and install process.
